swift - Binding NSPopUpButton to core data hangs Xcode build -

my environment:

• mac os x v 10.10.4
• version 6.4 (6e35b)

my project:

• mac app using swift 1.2 storyboard

a bit of background: got nstableview multiple columns hooked nsarraycontroller, in turn, hooked core data (say entity "car"). works - can load , edit column values, , save changes sqlite. of accomplished bindings via interface builder. want add new "color" column table, representing relationship entity, entity "color". each row have nspopupbutton new column; pop-up button should have values populated second nsarraycontroller linked "color" entity. thus, "color" many-to-one relationship between car , color (many cars can reference given color), , i'd values in pop-up button correspond "name" property color.

what i've done:

• in storyboard (under controller scene containing car table), i've added second nsarraycontroller, "colors array controller":

  1) under "attributes inspector" -> mode = entity name, entity name = color, "prepares content" checkbox selected

  2) under "bindings inspector" -> parameters -> managed object context -> "bind to" checked -> selected "cars controller" -> model key path = context

• in cars table (under nstablecellview), added nspopupbutton.

at point, builds , runs properly, except columns in table show "item 1" default value pop-up button (i can see other default values when expand pop-up).

now, i've tried following in futile attempt load pop-up correct values:

strategy 1:

using interface builder, selected nspopupbutton. under bindings inspector (value selection), checked "bind to" , specified colors array controller above; controller key -> arrangedobjects; model key path -> name

strategy 2:

• created iboutlet, "colorsarray", "colors array controller" in cars controller;
• using interface builder, selected nspopupbutton. under bindings inspector (value selection), checked "bind to" , specified cars controller; model key path -> colorsarray.arrangedobjects

for both of strategies above, whenever try run (or build) project, xcode hangs @ "compiling 1 of 1 storyboard files". activity monitor shows "ibtoold" process steadily consumes memory available (as kill it, xcode reports build failed).

i appreciate if shed light i'm doing wrong, or suggest alternatives achieve desired results.

i ran same issue: bind nspopupbutton's content binding arraycontroller's arrangedobjects xcode compile storyboard forever. when remove binding compile usual :(

since nspopupbutton inside table column, i've removed array controller , i'm binding content directly property of table column's object value.
