In my iOS Swift app I want to generate random UUID (GUID) strings for use as a table key, and this snippet appears to work:
let uuid = CFUUIDCreateString(nil, CFUUIDCreate(nil))
Is this safe?
Or is there perhaps a better (recommended) approach?
Try this one:
let uuid = NSUUID().uuidString
print(uuid)
Swift 3/4/5
let uuid = UUID().uuidString
print(uuid)
