Compilation under Xcode 13

[PFRene]

I'm getting loads of warnings when trying to compile this in the latest Xcode 13 RC (with Swift5) - mostly all errors are related to this sort of thing : "Argument type 'CBService?' does not conform to expected type 'CBUUIDConvertible'"

Any thoughts or suggestions? I'm having trouble working it out

EDIT: maybe helpful : If I open the same project into my saved copy of 12.5.1, it compiles the first try

Hello, I did a somewhat dirty fix (explicit unwrappings...) but I think it shouldn't cause any issue.

If you want, try with this branch https://github.com/jordanebelanger/SwiftyBluetooth/tree/swift5.5 until I finish merging the changes, need to make them backward compatible with Swift older than 5.5, that will take some time.

Thanks! The 5.5 branch will help in the mean time, at least it compiles again ;)

@jordanebelanger are you planning to do a proper fix and release a new version to support XCode 13 builds? thanks in advance

@Rolvar
I have a feeling that the current fix with the explicit unwrapping might be fine anyway and that it was just some sort of weird swift/objective-c evolution thing that led to the corebluetooth properties in question becoming optional.

Perhaps you or @PFRene can comment if you've been using the swift5.5 branch as to whether you've had any crashes using the new branch related to the new explicit unwrappings?

@jordanebelanger thanks for the quick reply, I've forked your code and you're right, seems to be something about how obj-c properties are being translated to optionals in swift, should be a better way, maybe use guard let instead? and make those throws an error that we can handle in production?

[jordanebelanger]

I don't wont to put unnecessary guard lets anywhere quite frankly I'd rather the program just crash if this is really some weird objective-c quirk.

Alright, I'll push a new cocoapods major release for this.

[jordanebelanger]

V3.0.0 is up and should fix xcode 13 related issues

Thanks @jordanebelanger 👏 🍻
