Missing required architecture arm64

[Talgat777]

Can't compile the project for IOS after importing this SDK. Error:

Could you try exclude arm64 arch on App level in XCode project? as currently we are excluding arm64 for iOS simulator on sdk level.

[FlurryDevNP]

Here are the build settings for excluded architecture

[jodymac]

Will the simulator be supported in the future? I can build to my device, but prefer to work in the simulator for the majority of the time and convenience

[blazer82]

Is there a workaround to keep working with the simulator or do we need to exclude the flurry dependency entirely on the simulator?

[FlurryDevNP]

Hello @jodymac and @blazer82 , you can try building the app on simulators with x86_64 architecture instead of arm64.

[blazer82]

@FlurryDevNP thanks for the suggestion. It did not work for me (or I did it wrong). Why do you need to exclude simulators anyway? I wouldn't even care if the library was disabled on simulators if it at least builds. Right now I need to maintain two branches of my code base - one with the flurry dependency in it and one without it - which isn't really sustainable in the long run.

[hantao-flurrydev]

@blazer82 This procedure is an accommodation for how our native iOS SDK's set up. Since M1 machine brings new simulator slice (arm64) so does XCode >=12 available archs, our iOS SDK is excluding arm64 in podspec settings in order for non M1 machine to build on simulators (simulators can still run on x86_64). So this might require users to exclude arm64 for simulator in the build settings, because by default it is available archs on xcode >=12.

I was unable to get your suggestion to work as well. I was a version behind, so I upgraded to the latest. Same result. I'm on Intel, macos Big sur 11.6.3, xcode 13.2.1. Perhaps more detailed instructions as even your screenshots didn't match mine. I can deal with having to run it on my device to test, but I don't want to have a second Flurry disabled branch/flavor solely just to be able to build and test all the other aspects of the app. I use the simulator quite frequently and test multiple screen sizes before uploading to testflight.

[hantao-flurrydev]

@jodymac @blazer82 sorry for this issue. I was testing this and found the arm64 should be excluded for pods target as well. The built framework skipped our native sdk excluded archs, so that have to do it manually on non M1 machine

@hantao-flurrydev thank you! This seems to work when starting the app in Xcode. Somehow the changes on the flutter_flurry_sdk target seem to get lost when executing flutter run however. Any idea what might be the cause for this?

[blazer82]

@hantao-flurrydev @Talgat777 @jodymac I could fix the issue by following the steps above and manually editing the file flutter_flurry_sdk.podspec.json inside the flutter_flurry_sdk. I also created a PR to hopefully fix this permanently.

I just changed

"EXCLUDED_ARCHS[sdk=iphonesimulator*]": "i386"

to

"EXCLUDED_ARCHS[sdk=iphonesimulator*]": "i386 arm64"

[jodymac]

Thanks everybody! The above workarounds have me working like I desired. Hassle free.
