is duplicated by:

  • SR-1138 Unsigned types display as signed in REPL (UInt8, UInt16, UInt32, UInt64)
  • SR-1751 Debugger shows data not matching the type of a variable

Issue Description:

For all unsigned integer types, the max property has a value of -1 instead of a correct positive value. However, when try to print these values, the output IS correct.

For example, in Swift REPL, UInt8.max is evaluated to -1, but print(UInt8.max) will generate the correct output, 255. Same applies to all other unsigned integer types.

How to reproduce:
1, launch Swift REPL
2, type UInt8.max

Comment by Enrico Granata (JIRA)

I believe so, yes. I remember an internal report of this, and it should be fixed in trunk.
