Converting Obj-C print statement to Swift's native "\variable name" syntax -


i want convert these 2 obj-c statements swift. i'm not sure syntax since there multiple object percent signs. have converted of code except print strings percent signs.

i want use swift's native print ("\variable") syntax.

self.validframes.text = [nsstring stringwithformat:@"valid frames: %d%%", min(100, (100 * self.validframecounter)/min_frames_for_filter_to_settle)];

validframes.text = string.localizedstringwithformat("valid frames: \min%%"(100, (100 * validframecounter) / minframesforfiltertosettle))

self.rate.text=[nsstring stringwithformat:@"%0.0f", beat];

rate.text = string.localizedstringwithformat("\beat 0.0f")

please correct swift syntax.

  1. the interpolation syntax \(expression):

    let validframespercentage = min(100, (100 * self.validframecounter)/min_frames_for_filter_to_settle) self.validframes.text = "valid frames: \(validframespercentage)%"

  2. you don't have control on how swift formats float if use interpolation syntax. example:

    let beat = float(10.0/3) self.rate.text = "\(beat)" // text 3.33333; can't specify number of digits

  3. if want use localized strings, can't use \(...) interpolation. perform interpolation, compiler has examine string. localized strings loaded data file @ runtime. compiler doesn't @ them.

  4. using format strings in swift 100% ok. part of library, uiview (or nsview).
