ios - Swift 2.0 'unexpected trailing closure' error with lazy var assignment -

-

i'm converting project swift 2.0 , keep coming across error everywhere i'm using lazy var. code works in 1.2 breaks in 2.0:

lazy private var placeholderimage = uiimage(named: "theimage")

but, code generates 'unexpected trailing closure' error in 2.0.

following xcode's suggestions fix error, come out with:

lazy private var placeholderimage: uiimage = uiimage(named: "theimage")!

this compiles , seems work, don't understand why change necessary in first place.

in apple developer forum apple staff (chrislattner) said:

yep, known bug (and reported) type inference isn't working lazy properties. adding explicit type annotation best way work around now.

the issue discussed in this google group
