With the GM version came the ability to change the column 2 text alignement. In the prior beta version, the text for the CLKComplicationTemplateModularLargeColumns template was showing up as expected from the Apple documentation: https://developer.apple.com/library/prerelease/watchos/documentation/ClockKit/Reference/CLKComplicationTemplateModularLargeColumns_class/index.html#//apple_ref/occ/instp/CLKComplicationTemplateModularLargeColumns/column2Alignment
Basic assumptions lead me to test the CLKComplicationColumnAlignmentLeft first of course to match the previous behavior. However, this yielded some unwanted results. The column2 text was now right aligned. I then tested both CLKComplicationColumnAlignmentRight (which aligned it slightly more to the right and off the screen) and having no text alignment specified (column 2 now covered column1). The below code shows a test left aligned template:
CLKComplicationTemplateModularLargeColumns *targetTemplate = [[CLKComplicationTemplateModularLargeColumns alloc] init];
targetTemplate.column2Alignment = CLKComplicationColumnAlignmentLeft;
targetTemplate.row1Column1TextProvider = [CLKSimpleTextProvider textProviderWithText:@"AAA"];
targetTemplate.row1Column2TextProvider = [CLKSimpleTextProvider textProviderWithText:@"1111"];
targetTemplate.row2Column1TextProvider = [CLKSimpleTextProvider textProviderWithText:@"BBB"];
targetTemplate.row2Column2TextProvider = [CLKSimpleTextProvider textProviderWithText:@"22222"];
targetTemplate.row3Column1TextProvider = [CLKSimpleTextProvider textProviderWithText:@"CCC"];
targetTemplate.row3Column2TextProvider = [CLKSimpleTextProvider textProviderWithText:@"333333"];
Column 1 works as expected, but the "22222" and "333333" would get truncated. Although the "1111" would fit, it it barely do so. My actual data can have more characters than any of these, so it will not work either. Any advice would be appreciated as the release is coming up soon.
Problem solved (sort of), the issue only occurred when building the application again after the mod large complication had been set to the clock face. The complication alignment works as expected for normal use. It probably shouldn't do this, but at least it shouldn't be an issue for the user.
