Crashes in simulator and iOS9

[hufkens]

Somehow since the last Xcode update (8.1) randomkit crashes for me when I run my app in the Simulator and also on iOS9 devices.I'm using the latest version 2.1.0 through CocoaPods. It worked before but somehow since the last update something changed/

The crash occurs in this method on the return statement:

extension UInt: RandomWithMax, RandomWithMin, RandomToValue, RandomThroughValue, RandomWithinRange, RandomWithinClosedRange {

    fileprivate var _resigned: UInt {
        return UInt(UIntMax(self)._resigned)
    }

}

Any help would be appreciated.

Can you tell me what MemoryLayout<UInt>.size and MemoryLayout<UIntMax>.size output for iOS 9 and the simulator?

[hufkens]

In the simulator and iOS9 device

MemoryLayout<UInt>.size -> 4
MemoryLayout<UIntMax>.size -> 8

On iOS10 device it is:

MemoryLayout<UInt>.size -> 8
MemoryLayout<UIntMax>.size -> 8

The crash is triggered bij the shuffled() func in the Shuffleable extension.

Hope that helps.

Let me know if 16c7833 fixes this issue

I now get a compiler error.

Integer+RandomKit.swift:257:25: Shift amount is greater than or equal to type size in bits

Ok, see if a1499bb fixes that

Looks like the crash is gone now in the Simulator. I haven't tested it yet on iOS9 but I'll keep you posted. Thanks a lot 👍

@hufkens what's the status for iOS 9? Can this issue be closed already?

[hufkens]

Just ran the app on an iOS9 Device and it worked.
Thanks a lot 👍
