i'm trying to convert source code developed in Xcode 6.4 into Xcode 7. I'm getting some new errors. Below code which works fine in Xcode 6.4 is not working in Xcode 7
for (index: String, category: JSON) in json["payload"]["categoryList"] {
let category:Category = Category(category : category)
categoryList.append(category)
}
Update your code like below,
for (index: String, cat: JSON) in json["payload"]["categoryList"] {
let category:Category = Category(category : cat)
categoryList.append(category)
}
It's good habit not to confuse the compiler by reusing variable names as parameter names and local variables in the same scope.
Better write:
for (index: String, category: JSON) in json["payload"]["categoryList"] {
let categoryListItem = Category(category : category)
categoryList.append(categoryListItem)
}
or even
for (index: String, category: JSON) in json["payload"]["categoryList"] {
categoryList.append(Category(category : category))
}
The type annotation Category
is not needed. The compiler infers the type
for (index: String, categoryJSON: JSON) in json["payload"]["categoryList"] {
let category:Category = Category(category : categoryJSON)
categoryList.append(category)
}
Actually i found answer for my question in swift 2.0 they changed syntax of for loop
for (key,categoryJSON):(String, JSON) in json {
//Do something you want
let category:Category = Category(category : categoryJSON)
categoryList.append(category)
}
