Hi,
I have a couple of design documents that holds some views for example a
document-types doc with theses views
...
if (typeof doc.type !== 'undefined') {
if (doc.type === 'foo') {
emit(doc.type, {
title: doc.title,
attribute: doc.attribute
});
}
else if (doc.type === 'bar') {
emit(doc.type, {
title: doc.title,
....
then I have a utility function that returns a compiled view (the current
working solution in Java ~ CouchUtils.java) that can be queried.
In swift I have a small starter problem i roughly do
let rev = database.existingDocumentWithID("_design/document-types")
let views = rev.propertyForKey("views")
Now when I try to look up the properties of `views` then I keep getting:
MyIOSAPP[26894:207053] -[__NSCFDictionary propertyForKey:]:
unrecognized selector sent to instance 0x7fcc99e9a7e0
I also get this error when trying out:
println(views.propertyList())
println(views.propertyName())
println(views.propertiesToSaveForDeletion())
Any hints appreciated !
Thx
Pelle
