ios - Swift: CGPathRelease and ARC -


just updated xcode beta 4, , noticed following compiler error code below:

var path = cgpathcreatemutable() ... cgpathrelease(path)

'cgpathrelease' unavailable: core foundation objects automatically memory managed

so remove release calls , should fine? or there more i'm missing? , there special cases should aware of arc?

the working cocoa data types section of using swift cocoa , objective-c says (emphasis mine):

core foundation objects returned annotated apis automatically memory managed in swift—you not need invoke cfretain, cfrelease, or cfautorelease functions yourself. if return core foundation objects own c functions , objective-c methods, annotate them either cf_returns_retained or cf_returns_not_retained.

…

when swift imports apis have not been annotated, compiler cannot automatically memory manage returned core foundation objects. swift wraps these returned core foundation objects in unmanaged<t> structure.

so yes, unless have unmanaged struct, correct , don't have worry manually releasing object.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
