The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.5.99.

Integrating Mantle in Xcode 12 via SPM:

Do you mind checking if setting the minimum deployment target to 9 is enough to resolve this issue? (I don't use SPM for ObjC dependencies and I wouldn't be surprised if it took more than that to make this work.)

[mathaeus]

@robb sorry for not mentioning this, deployment target is iOS 12.

From what I know the underlying problem is an Xcode problem and there have been equivalent issues in other SDKs, e.g. firebase/firebase-ios-sdk#6533
But since we are not using cocoapods anymore, I can't use a pod-post-install script to solve it.

Hmm, so there's nothing we can do? Would a precompiled XCFramework help? See #879.

This could be increased to .iOS(.v9),.

I would say it's safe to assume that people using SPM are using Xcode 12 and therefore the minimum deployment target is iOS 9. But again, this is just an assumption :)

I'm honestly not sure what #879 is asking for? 🤔

Haha, I completely forgot that we have a Package.swift 😵‍💫.

That sounds like a reasonably assumption. However, for this to work, we would also have to raise the minimum deployment target in the Xcode project, right? That would technically be a breaking change that required a new major version. I have a feeling that Mantle skews towards older apps. Do you happen to know if Apple still lets you submit iOS 8.0 apps to the store?

I think they are asking for the ability to download a zipped XCFramework from GitHub's release page. My understanding is that could also be used by SPM to download a binary artifact.

Doesn't look like:

Starting April 26, 2021, all iPhone and iPad apps submitted to the App Store must be built with Xcode 12 and the iOS 14 SDK or later

Xcode 12 has the minimum deployment target of iOS 9, hence also the warning.

Providing an xcframework would have the advantage that the target app wouldn't need to build the source code.

[robb]

I guess then there's little risk in bumping the minimum deployment target without a major version increase ¯_(ツ)_/¯ Would you mind filing a PR to that effect?

Yeah, I kinda want to offer this but I haven't made particularly great experiences with GH actions to automate this.

@robb sure, there you go #886

Closed in #886
