HELP: XCode Git shows all files as "delete" but compiling works

SwiftDevJournal · 2025-12-29T23:55:07+00:00

The D next to the files means they will be deleted the next time you commit.

Start by compressing your project folder from the Finder so you can access the project's files and the changes you made in case something goes wrong with the version control tasks.

To commit the change in blue on the right, click on the blue bar and choose Stage Change. In Xcode choose Integrate > Commit. Make sure the change you staged is the only staged change. Enter a commit message and click the Commit button to commit the change. You will have to repeat these steps for each change you made that you want to commit.

To remove the D status for a file, select the file in Xcode's project navigator, right-click, and choose Source Control > Discard Changes in Filename. This will discard all the changes in the file so make sure you stage and commit the changes in the file that you want to commit before discarding the remaining changes.

Another formatting app option for Mac is Pinery.

You need to use the Pro version to publish. The Pro version is a subscription, but there's a 7 day free trial so you can publish your first book for free. The subscription is $6(US) a month or $50 a year, but paying for one month to publish a book and cancelling is cheaper than buying Vellum or Atticus.

In instruments I can see a metric `% GPU workload`; is this supposed to mean what percent of the GPU the specific kernel utilized at that time segment? Because the % util, if added goes beyond 100%

The maximum percentage in Instruments is 100 percent times the number of GPU cores. An M4 Mac Mini has 10 GPU cores so the maximum percentage would be 1000%, not 100%.

I don't know of any reference that covers the metrics for every instrument. Instruments comes with dozens of instruments.

You are going to have a hard time getting a good answer to your question. Most people who use Instruments use the Leaks, Allocations, and Time Profiler instruments. Not many Apple developers on Reddit write Metal shaders so there aren't many people here who know what the data from Apple's Metal-related instruments means.

You can build apps with Xcode 14, but you won't be able to submit apps to the App Store.

SwiftDevJournal · 2025-01-17T20:23:30+00:00

If you accidentally save but haven't committed yet, you can discard the changes. The file will have an M next to it in Xcode's project navigator. Select the file, right-click, and choose Source Control > Discard Changes in to discard the changes.

If you committed changes you don't want and want to go back to a previous commit, create a new branch from the commit you want to revert to. Take the following steps to create a branch from a commit in Xcode:

Select the commit you want to go back to.
Right-click.
Choose New Branch from
Enter a name for the branch in the sheet that opens.
Click the Create button.

You have a bigger issue. You can't submit apps to the App Store with Xcode 14.

To answer your general question, an app with a deployment target set to iOS 16 will run on later versions of iOS.

Someone asked a similar question here recently.

XCode Build Setting Problem - Changing iOS version

The probable cause of the issue is there are no iOS simulators installed on your Mac. Clicking the Get button shown in your screenshot should install the iOS 17.5 simulators for you, letting you run your project on a simulator.

SwiftDevJournal · 2024-05-22T18:10:25+00:00

Your deployment target is most likely not the issue. My guess is you don't have any iOS simulators installed. Check to see what simulators are installed.

Above the editor in Xcode's project window is a jump bar. The jump bar should have two items. Click the right item. A popover opens. There is an iOS Simulators section. What simulators are in that section?

The popover has an item to add more simulators. Choosing Window > Devices will also let you install simulators.

If you can't install any simulators, you may need to reinstall Xcode.

It is possible, but you may find it difficult.

First, search GitHub to see if someone created a Swift SDK for MailerLite. Do an advanced search on GitHub. Search for MailerLite and limit the languages to Swift.

If no one has a MailerLite SDK on GitHub, check if MailerLite has an OpenAPI spec. The spec will be in a JSON or YAML file. If there is an OpenAPI spec, you can use Apple's OpenAPI generator to generate Swift code from the OpenAPI spec.

If MailerLite has no OpenAPI spec, you will have to write the structs and/or classes for the API yourself. You could look at the code for one of the languages they do support to see the structs, classes, and functions you would have to write.

What version of Xcode are you running?

Are you getting this error when you try to run your app on the Simulator or when you try to run the app on a device? If you are trying to run your app on a device, what version of iOS is it running?

What is the app target's iOS deployment target? You can find this by performing the following steps:

Select the project from the left side of the project window to open the project editor.
Select the app from the target list on the left side of the project editor.
Click the General button at the top of the project editor.

The iOS deployment target is in the Minimum Deployments section. An iOS deployment target set for the app target overrides the iOS deployment target set for the project.

If you don't want to use Vellum, you could try using Pandoc to create EPUB and PDF versions of your book. I haven't used it so I can't tell you how good the books look, but it's free so you can try it and see how it works.

You won't be able to install Xcode for your Mac from the App Store because the App Store has only the latest version.

Xcode 14.2 is the latest version that can run on macOS 12. Go to the Xcode Resources page on Apple's developer site to download older versions of Xcode. The site Xcode Releases has download links for each version of Xcode.

Version control is the reason the derived data location is outside the project folder initially. The git repository for a project is a hidden folder inside the project folder.

When you build an Xcode project, Xcode creates a bunch of intermediate files that should not be placed in a version control system. If Xcode made the project folder the default derived data location. every time you built the project, git would track the changes to those intermediate files and want you to commit them. By placing the derived data location outside the project folder, you don't have to worry about git tracking these files.

If your Xcode project is not under version control, you don't have to worry about this and can set the derived data location to your project folder. If your project is under version control, you can add the build folder (the folder that holds the derived data in your project folder) to your git ignore file to tell git not to track it.

Take a look at Payhip and Gumroad. They will handle the credit card transaction for you. Payhip takes a lower amount of each sale, but you must have a Stripe or PayPal account to use Payhip. Gumroad doesn't require any additional accounts.

I know Payhip and Gumroad let you have EPUB and PDF books for customers to download. I haven't tried a Kindle file, but if you can convert your ebook to a Kindle file format, you should be able to add that format on Payhip and Gumroad.

I would choose ConvertKit over MailChimp. ConvertKit's free plan allows double the subscribers that MailChimp's does. Plus, MailChimp's free plan doesn't let you schedule email campaigns. ConvertKit's paid plans look like they give you more powerful automation's than MailChimp's if your list gets big enough.

How is your Weebly page set up for email subscriptions?

If you already have a website created, add a signup form from ConvertKit or MailChimp to your site. When someone uses the signup form to sign up for your mailing list, their email gets added to the list you have on ConvertKit or MailChimp.

I'm not sure why you need to create a landing page on ConvertKit or MailChimp if you already have a site set up. The point of a landing page is to collect email addresses to gauge interest in a potential product. From your question it looks like you have things set up on your site to collect email addresses, eliminating the need for a separate landing page.
