Swift Adding HTML to UIWebView, expression was too complex - ios

Question

I'm adding some HTML content to an UIWebView.
This line:
generatedHtml += "<br><p style=\"font-family:'Chevin-Medium';font-size:12px;color:#505050;padding-top:0px;\">" + newsItem.entry.likes + " like this " + newsItem.entry.comments?.count + " comments</p>"
I get:
expressions was too complex to be solved in reasonable time
I'm just doing a count on an array, i don't know how to make that less complex?
The object looks like this:
public class NewsItem: NSObject {
var entry: EntryObject = EntryObject()
}
public class EntryObject: NSObject {
var comments: [Comment]? = []
}

Answer 1

newsItem.entry.comments?.count is an integer, and you can't add an integer to a string using +, you should use string interpolation with \():
" like this \(newsItem.entry.comments?.count) comments</p>"
Or use the String initializer if you need to keep using +:
" like this " + String(newsItem.entry.comments?.count) + " comments</p>"
If the error "too complex" persists, you'll have to break down the statements and use variables instead of inserting the expressions directly.

Answer 2

Try to do by this way
var countComments : Int = 0
//Validate comment counting
if let cComments = newsItem.entry.comments?.count
{
countComments = cComments
}
//... Some code here ...
//Devide to Conquest.
//If is easy to find... Is not hard to fix
generatedHtml += "<br>"
generatedHtml += "<p style=\"font-family:'Chevin-Medium';font-size:12px;color:#505050;padding-top:0px;\">"
generatedHtml += "\(newsItem.entry.likes) "
generatedHtml += "like this \(countComments) comments" //Here you have a valid value
genetatedHtml += "</p>"
But, why?
Maybe you have a problem with the optional value newsItem.entry.comments?.count that can gets you a nil value. Then, first of all, validate the value and be sure about what was returned. Better "0", a valid value than nil
When you split the string creation, the debug working will be more easy to execute. You will can have a better idea where is happening an error.
Maybe it´s not a definitive solution to your problem, but a good way to help you fix it.
