I've been developing a watchOS 2 complication for my app. It's looking great... asides from one last thing I'd like to tweak.
Complication templates seem to provide text alignment that isn't quite what I want. For the purpose of this question, let's go with the following code:
let template = CLKComplicationTemplateModularSmallStackText()
template.line1TextProvider = CLKSimpleTextProvider(text: "Hi")
template.line2TextProvider = CLKSimpleTextProvider(text: "Bye")
Unfortunately, you are limited by the predetermined layout that Apple has chosen for each particular template, and can't control the alignment.
Filing a bug report is your best option to address any issue or request an enhancement.
I can't reproduce your issue on watchOS 2.2 or 3.0 beta 1. line 2 is centered for that particular template.
