DEMO application crashes with Xcode 11.2

williehallock802 commented 4 years ago

I am not sure what is going wrong, but after I upgraded to Xcode 11.2, the demo application now crashes at:

extension EncodableRecord where Self: Encodable {
    public func encode(to container: inout PersistenceContainer) {
        let encoder = RecordEncoder<Self>(persistenceContainer: container)
        **try! encode(to: encoder)**
        container = encoder.persistenceContainer
    }
}

with

Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

I will assume that this is easily reproducible. If it is not, I can provide more information. The only relevant difference between when it was working and now seems to be the version of Xcode.

I am using the tip of master -- 416dda2

I did notice that the Demo app was using GRDB 4.4.0. I attempted to use GRDB 4.5.0, but the results were unchanged...still crashes.

Hello @williehallock802,

Thanks for reminding me of this. This crash is an Xcode bug. See https://github.com/groue/GRDB.swift/issues/640 for more information.

Please try the workaround explained in the above link: in the demo app Xcode project, select the app target, and set DEAD_CODE_STRIPPING to NO. It should fix the crash.

I should apply this workaround in the demo app so that other users do not face the same disappointment.

The workaround for the Xcode bug has been pushed to the master branch.
