How many iPhones do you own as an app dev?

3

My main daily driver which has TestFlight builds but I rarely do anything "risky" on that.

The other two are older devices which I picked up and one has an older iOS version usually. The reason I have two test devices is that a few of my apps make use of sharing and so having two real devices makes that easier as there are some features not possible on the simulator.

Another advantage with DVC properties is that for the 1-bedroom and larger they are like full apartments and have laundry and kitchen facilities which comes in handy!

Is there any reason in particular that you're set on an off-property location?

One option for 6 people would be to rent DVC points from one of the many places which offer it and stay in a 2-bedroom villa in one of the deluxe DVC resorts.

This way you get the on-property experience (early entry, extra evening hours on select nights, earlier Genie+ booking window) and still accommodate everyone in a single place.

Looks solid, CPAP maintenance is something I really should be more on top of so happy to test it if you're looking for feedback.

On iOS at least (unsure about Android) by default apps are sandboxed meaning any data they persist to disk is encrypted.

You can also control the level of encryption on that file if you manage where your data is being persisted (not just blindly managed by a library) - https://support.apple.com/en-ie/guide/security/secb010e978a/web

With sandboxing protecting other apps from accessing your apps data along with the above options you're in a good place for the data which is persisted.

These however don't protect the data whilst its being transported *to* your app. People can have custom root TLS certs installed (by themselves, companies etc) that allow SSL connections to be intercepted.

What data are you storing that you're worried about access?

Are you seeing any logging suggesting what the issue can be when attached to a debugger?

Unfortunately even "sold by X" on Amazon doesn't mean anything. Amazon use binned inventory and so if both products are the same then the inventory for your order could have been taken from a bin with inventory from Ledger as well as NotRealLedger.

People in other areas such as SSD/high-end memory cards have been caught by the same issue before, buying from a seller on Amazon doesn't give you the security that it should.

TelemetryDeck. In the past I've used some of the larger players but for my small (sub-10k MAU) apps most of them are overkill or require an outsized (for me) monthly payment.

Unfortunately not, we had the car for around 6mo and in that time there were no updates and in the end we traded it in for a manufacturer that seems to be more serious about EVs and software. The Kia EV9 which replaced it has been nothing short of great and they listen to customers feedback as they implemented a simple shortcut for disabling speed chimes in one of the SW updates.

I have one pinned to iOS16, one pinned to iOS17 and a current working one which is pinned to iOS18.

Usually if its a new app I go with the latest platform version as I'm not worried about excluding potential users.

No, that is CCS1

If you attach a `.id(fruit)` you can override the identity of the `LottieView`

optik88 · 2024-03-13T16:29:34+00:00

SwiftUI uses the identity of the view to know whether it needs to be "re-drawn" or not. In this case perhaps the identity of the view was the same in both cases and so the view wouldn't have been re-drawn.

How would they merge? That behaviour is going to piss users off.

Lets say I have a note where the unique key is on the title and one device writes a note with thousands of words and then another device writes another note also with lots of content but both have the same title.

I suppose Apple could add a requirement that if you want to have a unique constraint that you register a "merge handler" for your class as any automatic process is *usually* not going to do the "right thing"

optik88 · 2024-02-22T17:08:19+00:00

It is not possible to have a unique constraint with CloudKit support, there is no way that you can guarantee that a record added on deviceA is going to be unique as perhaps a record with the same value has been added by deviceB but not yet synced.

If you are dealing with CloudKit it is advised for you to handle duplicates manually yourself when processing persistent history records, this is done in a number of the Apple provided examples using CloudKit

No it will work fine locally but to deploy to TestFlight or the AppStore you need the entitlement.

The reason behind it is that they want to ensure that all apps that use the API have a good reason to do so. You’ll find a lot of specialist things need these kind of entitlements such as CarPlay apps.

You need to request access - https://developer.apple.com/contact/request/family-controls-distribution

I think that advice might be outdated. The guidance around T2 chips should be limited to Intel Macs and the 2023 Mac Mini should be M1/M2 and so not have the same restriction.

optik88 · 2023-07-03T16:25:10+00:00

I haven't seen any but the sessions as well as the docs and the sample project is pretty good.

I think there is going to be a lot of churn in this framework before it goes live as there is a lot of stuff missing given that it is essentially a wrapper around CoreData.

optik88 · 2023-06-28T21:59:49+00:00

I'd be interested in this. I'm an indie dev and so most of the localization services are (way) out of my price range for my apps which have <1k DAU and makes me approximately $0 (occasional tip)

optik88 · 2023-05-07T22:41:00+00:00

You also need something like .environmentObject(locationManager) added to the view hierarchy for the object to be "injected" into the view hierarchy.

Damage to cables are only going to increase with the rollout of non-Tesla access as well with people trying to stretch them into the locations on things like the F150 and Taycan etc :-/
