fatal error: load from misaligned raw pointer

Question

For iPhone5 (10.2) simulator this function:

static func fromByteArray<T>(_ value: [UInt8], _: T.Type) -> T {
        return value.withUnsafeBytes {
            $0.baseAddress!.load(as: T.self)
        }
    }

crashes at $0.baseAddress!.load(as: T.self) with this error:

fatal error: load from misaligned raw pointer

Does somebody know the solution?

I'm using this code:

EDIT it works for iPhone5s but not iPhone5

Indeed, it crashes as you described. The solution is to use this function to convert byte array to desired type:

func fromByteArray<T>(_ value: [UInt8], _: T.Type) -> T {
        return value.withUnsafeBufferPointer {
            $0.baseAddress!.withMemoryRebound(to: T.self, capacity: 1) {
                $0.pointee
            }
        }
    }

Here is my results from testing (red crashes the iPhone 5 simulator for unknown reason):
